What will happen to existing apps who use evaluateJavascript (with custom property added to window object) and upgrade to iOS 15? Won't they stop working?

  • -(void)webView:(WKWebView*)webView didFinishNavigation:(WKNavigation*)navigation

    After webVIew is loaded and then use evaluateJavascript to load custom properties can also be successful

I have meet the same error. Maybe the WKWebview function "evaluateJavaScript:" occurs some problems. Try another way to inject your code to solve this problem. For example

     WKUserScript *script = [[WKUserScript alloc] initWithSource:@"window.exeData = '1'" injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
    [webView.configuration.userContentController addUserScript:script];

Hope this way can help you.
